6 FAQs about [Flame retardant pp energy storage]
How can flame retardant polymer electrolytes improve the safety of Spes?
One influential strategy to improve the safety of SPEs is the use of flame-retardant polymer electrolytes (FRPEs) [, , , , , , , ]. By incorporating flame retardants into the polymer matrix, FRPEs can significantly reduce flammability, alter combustion behavior, and suppress thermal runaway .
Can flame retardants improve the performance of a battery?
Although adding flame retardants enhances fire resistance, it may negatively impact the SEI, resulting in degraded cycling performance. A promising alternative is grafting flame retardants onto polymer chains, which helps to minimize their adverse effects on the SEI and improves the electrochemical performance of the battery.
What are phosphorus based flame retardants?
This barrier helps to inhibit the spread of flames, thereby achieving condensed phase flame retardancy. Phosphorus-based flame retardants in polymer electrolytes can be classified into four types: small molecule plasticizers, organic solid flame retardants, reactive flame retardants, and inorganic flame retardants.
Can flame retardants be used in high-performance lithium batteries?
